Thanks Hans the new upload works with the gnuplot-module as it should be! Christian Am Mi., 25. Nov. 2020 um 14:25 Uhr schrieb Christian Prim < christian.prim@gmx.ch>:

Hi

with the latest version of lmtx (upgraded a minute ago), the gnuplot-example from the wiki-page (for lmtx with externalfigure) doesn't work. Error is:

tex error > tex error on line 1 in file virtual://buffer.svg-sin-inclusion.1: Undefined control sequence

The control sequence at the end of the top line of your error message was never \def'ed. You can just continue as I'll forget about whatever was undefined.

mtx-context | fatal error: return code: 256

here is the code:

gnuplot.tex: \usemodule[gnuplot]

\starttext \externalfigure[sin.gp][conversion=svg,width=4cm] \stoptext

sin.gp: set format xy "$%g$"

set title 'This is a plot of $y=\\sin(x)$' set xlabel 'This is the $x$ axis' set ylabel 'This is the $y$ axis'

plot [0:6.28] [0:1] sin(x)

The same code works on older lmtx (current version: 2020.09.20 23:02). It's not on the same linux-machine, but both have the same gnuplot-version installed.

Is this a bug?

Thanks Christian
